On/Off lyrics

I wish it could last But the moment slips into the past I blink and it moves beyond my grasp And then it's gone What does she expect? There's no way I can be perfect Now I'm trying to forget That she is gone I wish it could last But the moment slips into the past I blink and it moves beyond my grasp And then it's gone I can't see in black and white Instead it's different shades of grey It's hard to let go of yesterday When you're hanging on
